Specific embodiment
Below with reference to embodiment and attached drawing, the present invention will be described in detail, but the present invention is not limited to this.
Powder mixing device as shown in figs. 1 to 6, the cam machine of vibration rotation material box mechanism and top including lower part
Structure, and the spherical nail crushing, stirring mechanism three parts being placed between two parts.Its middle and lower part vibration rotation material box mechanism master
It to include vibrating motor (being not shown in the figure, connect with axis 111), pedestal 110 and magazine 108 (pedestal 110 and 108 groups of magazine
At dismountable back box)；Spherical shape nail crushing, stirring mechanism mainly includes the lifting platform 107 for being equipped with spherical nail 112, connecting rod
105 and reset spring 104；The cam mechanism on top mainly include cam 102, connecting shaft 101 and driving motor (in figure not
It shows, is connect with connecting shaft 101).
Vibration rotation the magazine course of work be vibrating motor drive 110 whirling vibration of pedestal, 108 outer wall of magazine have 2 it is convex
Platform 109 is engaged with the limiting slot of corresponding position in 110 top surface chamber of pedestal, therefore pedestal 110 will drive the synchronous rotation of magazine 108
Turn.
Spherical shape nail crushing, stirring mechanism is mounted in rack 106, and connecting rod 105 in rack 106 by passing through；Reset spring
104 lower end resists rack 106, and upper end resists the top plate 103 being bonded with 102 circumferential surface of cam.Spherical shape nail crushing, stirring mechanism, does
It moves back and forth, a circulation includes lifting, falling, and a period of time can be maintained after falling, lifts and falls mainly pulverization, fall
It is mainly stirring action that a period of time is kept after lower.The bulb 113 of 112 lower ends of spherical shape nail can increase the area of crushing, simultaneously
Cooperate the vibration of magazine 108 to rotate to guarantee not generate new agglomeration, the lattice of material can also not destroyed as far as possible.Spherical shape nail
112 see Fig. 5 with the relative positional relationship of magazine 108, and a indicates that spherical nail 112 is in falling state in Fig. 5, and b indicates ball in Fig. 5
Staple 112 is in lifting status.Reset spring 104 makes the top plate of 105 upper end of connecting rod keep 103 to contact with cam 102, simultaneously
It can also play the role of buffering.
The cam mechanism on top provides power for spherical nailing machine structure, and driving motor is through connecting shaft 101 with 102 turns of moving cam
Dynamic, the shape and motion profile figure of cam 102 are shown in that Fig. 3 and Fig. 4, cosine acceleration motion curve can reduce impact, movement
Trajectory diagram, which can be seen that, to stop and can continue for some time far, and spherical shape this period nail is located at extreme lower position, contacts magazine bottom,
Magazine is in vibration rotation status, therefore realizes agitating function.It should be noted that the position between magazine 108 and pedestal 110
The relationship of relationship and 102 stroke of cam, it is ensured that when spherical shape nail 112 is in the top lifted, magazine 108 can be from pedestal 110
On take off.
Entire operation process are as follows: 1. initial positions make spherical nail 112 in topmost (cam 102 closely stops to be followed closely with spherical
Mechanism upper end face contact)；2. being put into after different materials is weighed according to certain specific gravity in magazine 108, by 108 sets of magazine
On spherical shape nail 112；3. pedestal 110 is moved to lower section, engage magazine 108 with pedestal 110 downwards, and vibrating motor and drive
Dynamic motor, is stirred crushing；4. turning off vibrating motor and driving motor after mixing a period of time, pay attention to making spherical nail 112
In topmost, and magazine 108 is removed in the way of feeding, operating process is as shown in Figure 6.
The foregoing is merely preferable implementation examples of the invention, are not intended to restrict the invention, it is all in spirit of that invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
